There are several ways to build solid walls using just mud or clay, but the most extensively used method has been the forming of bricks out of mud or clay, and, after some preliminary air drying or sun drying, they are laid in the wall in mud mortar.
196. (T-9-Q26) (OG12-11) There are several ways to build solid walls using just mud or clay, but the most extensively used method has been the forming of bricks out of mud or clay, and, after some preliminary air drying or sun drying, they are laid in the wall in mud mortar. A. the forming of bricks out of mud or clay, and, after some preliminary air drying or sun drying, they are laid B. forming the mud or clay into bricks, and, after some preliminary air drying or sun drying, to lay them C. having bricks formed from mud or clay, and, after some preliminary air drying or sun drying, they were laid D. to form the mud or clay into bricks, and, after some preliminary air drying or sun drying, to lay them E. that bricks were formed from mud or clay, which, after some preliminary air drying or sun drying, were laid 选项分析： A. the method与the forming不对等；the forming of bricks out of mud or clay和they are laid in the wall in mud mortar不平行；they指代不明 B. forming the mud or clay into bricks与to lay them不平行 C. having bricks formed from mud or clay, they were laid不平行 D. Correct；本题主考平行；several ways可以与there be搭配；A method is to do X and to do Y常见搭配；and后面加上逗号的表达并不常见，从本题可见GMAT接受这样的用法(prep1-247也出现类似用法) E. Which指代错误，它无法跨越谓语动词指向bricks；一般过去时错误 C项我是因为看and后面是 ing 所以选的C ，我想问难道平行不应该和and 后面也要平行么？（如果不看to lay them） 平行应该怎么看呢？
and 行平兩個動作，to form the mud or clay into bricks , 跟 to lay them in the wall in mud mortar. 而after some preliminary air drying or sun drying, 是插入句，被充說明而已，況且air drying , sun drying 是名詞，不是表動作。 另外，你可以從and 前後的逗號及 after...drying前後的逗號發現，這一句只是插入句，就算拿掉也不影嚮主結構!!
